FIELD

Various embodiments of the disclosure relate to cognitive search, artificial intelligence, and user interfaces for the cognitive search. More specifically, various embodiments of the disclosure relate to an electronic device and method for providing a user interface for a cognitive search in content.

BACKGROUND

Advancements in the field of artificial intelligence (AI) have led to development of sophisticated search tools that use AI to perform searches within a corpus of content. Typically, a search tool provides a user interface (UI) through which a user can input a search query. The search query may be shared with a search engine that may perform the search based on keywords or other parameters associated with the query. For a search within content of several content files, search UIs can include options to configure complex search queries. In many cases, the options presented on conventional search UIs may be limited to a regular expression, keyword-based content filtering options, or options that sort the search results based on few sorting parameters.

Limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

DETAILED DESCRIPTION

The following described implementations may be found in the disclosed system and method for rendering an application interface for cognitive search in content. Exemplary aspects of the disclosure provide an electronic device. For example, the electronic device may be a smartphone or a laptop of a user. The electronic device may be configured to control a display device to render the application interface that may include user Interface (UI) elements. The UI elements may include a first UI element to select a set of media items. The set of media items may include various types of media items, such as videos, audios, images, and/or a combination thereof. For example, the set of media items may include clips of one or more movies or programs. In accordance with an embodiment, the set of media items may include virtually created artefacts if the search is for a created scene (e.g., a game). For example, the search may be performed to look for a particular 3D model or texture in a VR scene.

The UI elements may further include a second UI element to select input data to be used for a search inside content and/or associated metadata of each media item of the set of media items. In some embodiments, the input data may include an image, a text, an audio clip, or a video clip. In some other embodiments, the input data may include other sensor inputs, such as static or dynamic point clouds, 3D video clips, texture maps, bio signals, AR/VR content, medical data (such as MRI images, CT scans, or Ultrasound images), spectrograms, RADAR images, or a combination thereof. For example, the input data to be used for the search inside the content may be an image or an audio clip of an actor who may have acted in one or more movies. The UI elements may further include a set of interactive UI elements to configure parameters that may control at least one of a search inside the content or a metasearch within results of the search. Examples of the parameters may include, but are not limited to, a confidence score applicable on the search, an accuracy of the search result, a similarity score that measures a degree of similarity between the search result and the input data, an affinity score, and a proximity score. The set of interactive UI elements may correspond to, for example, sliders, a checkbox, an equalizer, a checkbox with a slider, a movable dial, and the like. Additionally, or alternatively, the set of interactive UI elements may include a graph with user-configurable nodes representing the parameters and the input data.

In accordance with an embodiment, the set of interactive UI elements may include one or more UI elements to specify a data structure that can be generated from a sensory input, such as tactile, aromatic, haptic, or olfactory input. Such inputs can be used as parameters of the search to be performed in the content or associated metadata of each media item of the set of media items.

The electronic device may further receive a user input via the UI elements of the application interface. The user input may be utilized to fine tune the parameters and the input data. In an exemplary scenario, the parameters and the input data may be fine-tuned by the user. For example, the sliders may be utilized by the user to set the confidence score, the similarity score, and the affinity score. Based on the user input, the electronic device may transmit a search request to a search engine system and may receive a search result corresponding to the search request from the search engine system. The search result may identify, from within the content or associated metadata, one or more content elements that match the input data and satisfy the parameters included in the user input. For example, the search result may include one or more frames (selected from frames) of the selected set of clips of movies that may match the selected input data (such as the image of the actor). The electronic device may control the display device to render the search result onto a result UI of the application interface.

Conventionally, search tools provide a UI through which a user can input a search query. The search query may be shared with a search engine that may perform the search based on keywords or other parameters associated with the query. For a search within content of several content files, search UIs can include options to configure complex search queries. In many cases, the options presented on conventional search UIs may be limited to a regular expression, keyword-based content filtering options, or options that sort the search results based on few sorting parameters. In contrast, the present disclosure provides an improved UI to configure a search query for a search inside content of media items or a metasearch within results of the search. The improved UI may allow a user to fine tune certain parameters associated with the search as well as the input data. Instead of relying on few conventional options, the improved UI offers various cognitive parameters related to the use of AI model(s) in the search. For instance, through the UI, the user may set desired range or value for parameters, such as accuracy, proximity, or similarity. In addition to cognitive parameters, the improved UI may provide UI elements, such as sliders, checkboxes, or a configurable graph to define content-specific parameters which may be related to machine learning task(s) implemented in the search. For example, if the search is to be performed to look for images within video clips that have certain types of face expression, then the improved UI may display options to select various emotion types and set weightages of selected emotion types. The UI elements presented on the improved UI may improve a user's ability to create focused search queries that provide more accurate and focused results. The improved UI may save user's effort in the search, which may otherwise be required on conventional UIs of search tools.

Details of the selection of the AI model of the AI models 128 are further described, for example, in FIG. 4 .

In accordance with an embodiment, the set of interactive UI elements 122 may include a first UI element that may be rendered on the display device 108 as a graph with user-configurable nodes representing the parameters and the input data 126. The user-configurable nodes may be connected via a plurality of edges. Each user-configurable nodes may be of an adjustable size which may indicate an importance of the respective node. Each edge of the plurality of edges may be of an adjustable length, which may depict the confidence score between two connecting nodes of the user-configurable nodes. Moreover, a connection of two or more nodes of the user-configurable nodes may indicate a co-occurrence factor to be used in the search.

The set of media items 308, including a first media item 308A and a second media item 308B may be images, text documents, audio clips, video clips, or a combination thereof. For example, the first media item 308A and the second media item 308B may be video clips associated with one or more movies of an actor. The first media item 308A and the second media item 308B may be selected using the add element 310. The add element 310 may be selected to upload or specify the selection of the set of media items 308. Similarly, other media items may be selected using the add element 310. The first UI element 306 may include an option to select metadata 310A associated with the set of media items 308 for the search. The metadata 310A may include information about the content of each media item. For example, for a video file, the metadata 310A may be video metadata that includes information, such as but not limited to, an author name, a date of creation, a location where the video is shot, camera information, and an upload date.

In accordance with an embodiment, the set of media items 308 may include virtually created artefacts if the search is for a created scene (e.g., a game). For example, the search may be performed to look for a particular 3D model or texture in a VR scene. In accordance with another embodiment, the set of media items 308 may include static or dynamic point clouds, 3D videos, texture maps, bio signals, AR/VR content, medical data (such as MRI images, CT scans, or Ultrasound images), spectrograms, RADAR images, or a combination thereof.

The second UI element 312 may be utilized by the user to select the input data 314 to be used for a search inside content or the associated metadata (such as the metadata 310A) of each media item, such as the first media item 308A and the second media item 308B of the set of media items 308. In accordance with an embodiment, the input data 314 may include an image, a text, an audio clip, a video clip, or a combination thereof. For example, the input data 314 may include a first image 314A of the first actor in a specific pose, expressing a specific emotion. In accordance with an embodiment, the input data 314 may include other sensor inputs, such as static or dynamic point clouds, 3D video clips, texture maps, bio signals, AR/VR content, medical data (such as MRI images, CT scans, or Ultrasound images), spectrograms, RADAR images, or a combination thereof.

The add image element 314B may be utilized by the user to add other to be in the input data 314. For example, the add image element 314B may be clicked by the user to add other images of the first actor or a second actor different from the first actor. The selected input data 314, such as the first image 314A may need to be used for the search inside the content of each media item of the selected set of media items 308, such as the video clips associated with one or more movies of the first actor. The set of interactive UI elements 316 may be utilized by the user to configure the parameters that may control a search inside the content (such as the set of media items 308) or a metasearch within results of the search.

In accordance with an embodiment, the circuitry 202 may receive an input via the application interface 302. The input may be, for example, a part of the input data 314 and may correspond to a text that includes one or more keywords. In an exemplary scenario, the keywords may include a name of a first actor and a facial expression of the first actor. For example, the input may be a phrase “Tom Hanks laughing in front of a building in a black suit”. Based on the or more keywords included in the received input, the circuitry 202 may determine the parameters available for the search or the metasearch.

In accordance with an embodiment, the parameters may include a confidence score applicable on the search or on the AI models 128 to be used in the search. The confidence score(s) may be set by the user and may lie in a range of 0 to 1 or 0% to 100%. The confidence score may depict a confidence level of each of the AI models 128 in generation of a search result (such as the search result 328).

The parameters may further include an accuracy of the search result 328 or of one of the AI models 128 to be used in the search. The accuracy may be set by the user. In accordance with an embodiment, the accuracy may be set based on an initial search result rendered on the result UI 326. The initial search result may be rendered on the result UI 326 based on the input data 314 selected by the user. In an exemplary scenario, the input data 314 may include the image of the first actor with a happy facial expression. The initial search result may include images of the first actor with a sad facial expression. As the initial search result may include the images of the first actor but with a different facial expression as required by the user, the accuracy may be set according to a user preference, such that consecutive search results may include the images of the first actor with the happy facial expression.

The parameters may further include a similarity score that may measure a degree of similarity between the search result 328 and the input data 314. For instance, the similarity score may be set by the user in order to search for images in the media item(s) that may be like the images included in the input data 314. As an example, the input data 314 may include an image of an actor in front of a building. The similarity score may be set by the user to search for images from within the set of media items 308 that depict the actor in front of a building.

The parameters may further include an affinity score and the proximity score. The affinity score and the proximity score may be other parameters that may be set by the user to define a degree of closeness between the input data 314 and the search result 328. Further, the parameters may include a first contribution weightage to be associated with each of the confidence score, the accuracy, the similarity score, the affinity score, and the proximity score. For example, the first contribution weightage may be set by the user by selection of a numeric value, or a numeric range associated with each of the confidence score, the accuracy, the similarity score, the affinity score, and the proximity score.

The parameters may further include a content-specific parameter associated with a machine learning task to be used in the search. For example, the content-specific parameter may be determined based on the input data 314 or the one or more keywords associated with the received input. In an exemplary scenario, the input data 314 may include the image of an actor, such as “Tom Hanks” with a laughing expression and an actress. The content-specific parameter may include the parameters, such as “sad”, “happy”, “surprise”, and so forth. The parameters may include a second weightage to be associated with the content-specific parameter. In case of multiple parameter values (such as sad, happy, and surprise), the second weightage may include a weight assigned to each value of the content-specific parameter. For example, for the image of the actor “Tom Hanks” with a laughing expression, the second weightage assigned to a content-specific parameter value “happy” may be more than the content-specific parameter value “sad”.

In accordance with an embodiment, the input data 314 may include a face image or a first audio clip of a person (such as an actor). In such a case, the content-specific parameter may correspond to a weighted combination of multiple emotion types to be used in the search. For example, the first audio clip may include a dialogue between the first actor and an actress. The emotions in the first audio clip may be recognized by the selected AI model (of the AI models 128) to determine the content-specific parameters. The multiple emotions recognized by the AI model may be utilized to generate the parameters. For example, the equalizer 322 may depict multiple emotions and may be utilized by the user to set the second weightage. The second weightage may be set to determine a weighted combination of multiple emotion types to be used in the search.

After the application interface 302 is rendered, the circuitry 202 may receive a user input via the UI elements 304 of the application interface 302. In an exemplary scenario, the first media item 308A and the second media item 308B may be selected by the user for a search. The first image 314A may be selected as the input data 314 that may need to be used for a search inside content of the first media item 308A and the second media item 308B. The sliders 318 may include a first slider 318A to set the similarity score. The sliders 318 may include a second slider 318B to set the confidence score. The sliders 318 may include an Nth slider 318N to set the accuracy. Based on a type of search required by the user, the first slider 318A, the second slider 318B, and the Nth slider 318N may be adjusted by the user. Each of the first slider 318A, the second slider 318B and the Nth slider 318N can be set to have a value within a numeric range, such as 0 to 1 to set a first contribution weightage associated with the similarity score, the confidence score, and the accuracy.

The checkbox 320 may depict the content-specific parameters. The checkbox 320 may include a first checkbox 320A corresponding to an emotion “happy”, a second checkbox 320B corresponding to an emotion “sad”, and a third checkbox 320C corresponding to an emotion “angry”. The checkbox 320 may further include a fourth checkbox 320D corresponding to an emotion “surprise” and fifth checkbox 320E corresponding to an emotion “neutral”. In an exemplary scenario, the first checkbox 320A corresponding to the emotion “happy” and the fourth checkbox 320D corresponding to the emotion “surprise” may be selected by the user, based on the first image 314A included in the input data 314. In another exemplary scenario, the first image 314A may depict the first actor with a “sad” facial expression. The user may require searching for the images of the first actor with a different facial expression, such as an “angry” facial expression in the set of media items 308. In such a case, the similarity score may be set low, such as between “0.4 to 0.6” as the required search may include the images of the first actor but with the different facial expression. Further, the third checkbox 320C corresponding to the emotion “angry” may be selected by the user.

For the content-specific parameters depicted in the checkbox 320, the equalizer 322 may be utilized to set the second weightage associated with the content-specific parameters. For example, the equalizer 322 may include a first equalizer 322A corresponding to the emotion “happy”. The equalizer 322 may include a second equalizer 322B corresponding to the emotion “surprise”. The equalizer 322 may include an Nth equalizer 322N corresponding to the emotion “neutral”. Each equalizer of the equalizer 322 may be utilized to set the second weightage. The numeric range of the second weightage may be between 0 to 1. The second weightage may be assigned based on an amount of emotion associated with individual items (e.g., in image frames or in specific audio portions of video clips) of the search result 328.

The movable dials 324 may include a first dial 324A to set the confidence score and a second dial 324B to set the accuracy. Similarly, the movable dials 324 may include other dials corresponding to the similarity score and the proximity score. Each dial of the movable dials 324 may be set to a value within a range, such as a percentage between 0% and 100%. For example, the percentage of the confidence score required by the user may be set by turning the first dial 324A. Similarly, the percentage of the accuracy required by the user may be set by turning the second dial 324B.

The circuitry 202 may be further configured to transmit the search request to the search engine system 104, based on the user input. The circuitry 202 may receive the search result 328 corresponding to the search request from the search engine system 104. The search result may identify, from within the content or associated metadata (such as the metadata 310A), one or more content elements that may match the input data 314 and may satisfy the parameters included in the user input. The circuitry 202 may control the display device 108 to render the search result 328 onto the result UI 326 of the application interface 302.

In some embodiments, the one or more content elements may include one or more images (such as image frames) that may be retrieved from the first media item 308A and the second media item 308B. Such images may match the first image 314A of the input data 314. By way of example, and not limitation, the search result 328 may include a first frame 328A, a second frame 328B, and an Nth frame 328N. In an exemplary scenario, each of the first frame 328A, the second frame 328B, and the Nth frame 328N may include the face of an actor with a specific face expression that matches the face expression of the actor in the first image 314A of the input data 314.

In accordance with an embodiment, the search engine system 104 may execute a search based on the search request. The search engine system 104 may be configured to execute a search inside the content of each media item of the set of media items 308 to generate an initial search result. The search may be executed based on the input data 314 by a selected AI model of the AI models 128. Moreover, the search may be a machine learning task to look-up, within the content, a set of content elements that may match the input data 314. In one or more embodiments, the search engine system 104 may generate the initial search result based on the input data 314, such as the first image 314A. The initial search result may include one or more images related to the first image 314A.

In accordance with an embodiment, the machine learning task may be a classification task of emotion recognition and the selected AI model of the AI models 128 may be trained on the classification task of emotion recognition. For example, the first image 314A of the input data 314 may be an image of the first actor with a smiling facial expression. The AI model may recognize the emotion as “happy” corresponding to the smiling facial expression. The machine learning task may be to look-up, within the content, a set of content elements that may include the images of the first actor with a happy emotion.

In some instances, not all the images in the initial search result may match the first image 314A (or the face expression associated with the first image 314A). In such a case, the initial search result may be determined to be a broad result that may need to be filtered to obtain a more accurate result that satisfies the parameters specified through the user input. In accordance with an embodiment, the search engine system 104 may be further configured to execute a metasearch to filter the set of content elements in the initial search result. The set of content elements may be filtered based on the parameters in the user input, to determine the one or more content elements of the search result 328. If the initial search result is broad in nature, the metasearch may be executed by the search engine system 104 to filter the set of content elements in the initial search result. In some embodiments, the initial search result may be rendered on the result UI 326. The user may analyze the initial search result to configure the parameters. Based on the configured parameters, the circuitry 202 may render the search result 328, such as the first frame 328A, the second frame 328B, and the Nth frame 328N as the one or more content elements of the search result 328.

In accordance with an embodiment, the input data 314 may include the face image of the person, such as an actor. The one or more content items of the search result 328 may include at least one image that may be from within the content and may match the emotion or the face expression of the person in the face image. In an exemplary scenario, the first image 314A may be the face image of the actor. The one or more content items, such as the first frame 328A, the second frame 328B, and the Nth frame 328N may depict the same emotion or the face expression as depicted in the first image 314A of the input data 314.

FIG. 4 is a diagram of an exemplary application interface that illustrates a selection of an artificial intelligence (AI) model, in accordance with an embodiment of the disclosure. FIG. 4 is described in conjunction with elements from FIGS. 1, 2, and 3 . With reference to FIG. 4 , there is shown a diagram 400. The diagram 400 may include the application interface 302.

The application interface 302 may include the UI elements 304. The UI elements 304 may include a third UI element 402. The third UI element 402 may include a list of the AI models 128.

The audio file 410 and other audio files may be uploaded via an upload element 412. Similarly, the audio file 410 and the other audio files may be merged via an audio equalizer 414. In accordance with an embodiment, an audio input may be received from a microphone (i.e., an audio sensor) instead of the audio file 410. The received audio input may be processed and converted to a file, which may be treated as the input data 314. The search may be performed using the file.

In accordance with an embodiment, the third UI element 402 may be utilized by the user to select an AI model that may be suitable for a machine learning task from the AI models 128. The user input may include a selection of the AI model from a list of different AI models 128 displayed in the third UI element 402. In some embodiments, a first AI model 402A of the AI models 128 may be trained on a task of emotion recognition based on the facial expressions of persons in images. A second AI model 402B of the AI models 128 may be trained on a task of emotion recognition based on an input audio. A third AI model 402C of the AI models 128 may be trained on the task of emotion recognition based on an input text (or verbal expression). Based on the type of data included in the input data 314, the required AI model of the AI models 128 may be selected by the user.

The audio inference element 404 may be utilized by the user to select one or more audio files, such as a first audio file 404A and a second audio file 404B. The selection of the first audio file 404A and the second audio file 404B may be performed via the add element 406. In some instances, the selected first audio file 404A and the second audio file 404B may be utilized to configure the selected AI model of the AI models 128. The configured AI model element 408 may be used by the user to select and configure the AI model of the AI models 128 displayed on the third UI element 402.

In accordance with an embodiment, the input data 314 may include a first audio clip, such as the audio file 410 of the person (such as the first actor). The one or more content items of the search result 328 may include at least one image or a second audio clip that may be from within the content and may match the emotion expressed by the person in the first audio clip (such as the audio file 410). In an exemplary scenario, the first audio clip may include a dialogue between the first actor and a second actor of a movie. The selected AI model of the AI models 128 may classify the emotions expressed by the person in the first audio clip as “surprise” and “happy”. Based on the classified emotion(s), the circuitry 202 may receive the search result 328 that may include the one or more images or a second audio clip that matches the emotions “surprise” and “happy”. In some embodiments, the input data 314 may include multiple audio files. The audio equalizer 414 may be utilized by the used to merge and create composite audio files to be used for a search in the content.

FIG. 5 is a diagram of an exemplary application interface that illustrates a graph with user-configurable nodes, in accordance with an embodiment of the disclosure. FIG. 5 is described in conjunction with elements from FIGS. 1, 2, 3, and 4 . With reference to FIG. 5 , there is shown a diagram 500. The diagram 500 includes the application interface 302.

The application interface 302 may include the UI elements 304. The UI elements 304 may include a graph 502. The graph 502 may include user-configurable nodes 504 and a plurality of edges 506. The UI elements 304 may further include the set of interactive UI elements 316. The set of interactive UI elements 316 may further include a checkbox with a slider 508. In accordance with an embodiment, the set of interactive UI elements 316 may include a first UI element that may be rendered on the display device 108 as the graph 502 with the user-configurable nodes 504 representing the parameters and the input data 314. The user-configurable nodes 504 may be connected via the plurality of edges 506.

The user-configurable nodes 504 may include a first node 504A corresponding to the parameter “celebrity”, a second node 504B corresponding to an image of the first actor (associated with the parameter “celebrity”), and a third node 504C corresponding to an image of a first actress (associated with the same parameter “celebrity”). The user-configurable nodes 504 may further include a fourth node 504D corresponding to a parameter “emotion”, a fifth node 504E corresponding to a first value (i.e., “happy”) of the parameter “emotion”, and a sixth node 504F corresponding to a second value (i.e., “sad”) of the parameter “emotion”. The user-configurable nodes 504 may further include a seventh node 504G corresponding to the input data 314 (represented by “audio”), an eighth node 504H corresponding to a first audio type “background music” of the input data 314, and a ninth node 504I corresponding to a second audio type “Foley audio” of the input data 314.

As shown, for example, the plurality of edges 506 may include a first edge 506A between the first node 504A and the third node 504C, a second edge 506B between the first node 504A and the second node 504B, a third edge 506C between the second node 504B and the fourth node 504D, and a fourth edge 506D between the third node 504C and the fourth node 504D. The plurality of edges 506 may further include a fifth edge 506E between the fourth node 504D and the fifth node 504E, a sixth edge 506F between the fourth node 504D and the sixth node 504F, a seventh edge 506G between the third node 504C and the seventh node 504G, an eighth edge 506H between the seventh node 504G and the eighth node 504H, and a ninth edge 506I between the seventh node 504G and the ninth node 504I.

Each of user-configurable nodes 504 may be of an adjustable size which may indicate an importance of the respective node. For example, a size of the node (such as the third node 504C) may be more than a size of a node (such as the second node 504B). In such a case, an importance of the third node 504C may be more than an importance of the second node 504B. The size of each node may be adjusted by the user to obtain a desired search result (such as the search result 328). For example, in case the importance of appearance of the celebrity depicted at the third node 504C is more than that of the celebrity depicted at the second node 504B, the size of the third node 504C may be made larger than the size of the second node 504B.

Each edge of the plurality of edges 506 may be of an adjustable length which may depict the confidence score between two connecting nodes of the user-configurable nodes 504. For example, the length between the fourth node 504D corresponding to the parameter “emotion” and the fifth node 504E corresponding to the first emotion “happy” may be less than the length between the fourth node 504D corresponding to the parameter “emotion” and the sixth node 504F corresponding to the second emotion “sad”. In such a case, the confidence score of the emotion “happy” may be more than the confidence score of the emotion “sad”. Therefore, the search result 328 may include the one or more images that depict the first actor and the first actress as happy.

The connection of two or more nodes of the user-configurable nodes 504 may indicate a co-occurrence factor to be used in the search. For example, the connection between the second node 504B corresponding to the image of the first actor and the third node 504C corresponding to the image of the first actress may indicate the co-occurrence factor to be used in the search. In such a case, the search result 328 may include the one or more images that include both the first actor and the first actress together in one frame.

In some embodiments, the content-specific parameter “emotion” may be selected, and the second weightage associated with the content-specific parameter “emotion” may be provided by the user by use of the checkbox with a slider 508. For example, the second weightage corresponding to the emotion “happy” may be set by the user via a checkbox with a slider 508A and the second weightage corresponding to the emotion “surprise” may be set by the user via a checkbox with a slider 508B.

In accordance with an embodiment, the circuitry 202 may be configured to receive the search result corresponding to the search request from the search engine system 104. The search result 130 identifies, from within the content or associated metadata, one or more content elements that may match the input data 126 and satisfy the parameters included in the user input. Details of the reception of the search result corresponding to the search request from the search engine system 104, are further described, for example, in FIG. 3 .

At 612, the display device 108 may be controlled to render the search result 130 onto the result UI 114 of the application interface 110. In accordance with an embodiment, the circuitry 202 may be configured to control the display device 108 to render the search result 130 onto the result UI 114 of the application interface 110. Details of the control of the display device 108 to render the search result 130 onto the result UI 114 of the application interface 110, are further described, for example, in FIG. 3 .

Although the flowchart 600 illustrates discrete operations, such as 604, 606, 608, 610, and 612 the disclosure is not so limited. Accordingly, in certain embodiments, such discrete operations may be further divided into additional operations, combined into fewer operations, or eliminated, depending on the implementation without detracting from the essence of the disclosed embodiments.
